CPU Cooler be quiet! PURE ROCK SLIM 3 - BK047

be quiet! PURE ROCK SLIM 3 is a compact air CPU cooler aimed at budget and mid-range configurations, where you seek a balance between silence and sufficient cooling. It fits modern platforms with support for LGA 1700, LGA 1851, AM4, and AM5, so you can safely use it even for a future upgrade. With a 100 mm fan and a standard 4 PIN connector, installation is easy in most cases and motherboards. The black color makes it discreet and suitable for clean builds without flashy lights.

What you get: Air cooling with a 100 x 100 x 25 mm fan, which provides a good compromise between size and airflow – useful if you use a more compact case or a microATX/mini-ITX motherboard. The speed range from 700 to 1700 RPM gives you flexibility – at lower speeds, the system runs quieter, while under load, the fan can „spin up“ for better temperature control. The Rifle Bearing is a step up from ordinary sleeve bearings, offering better durability and more stable operation under prolonged load. The declared 24.8 dBA means that even under load, the cooler remains relatively quiet, which is important if you keep the machine close to you on your desk. Thanks to the standard 4 PIN connector, you can use PWM control via the motherboard and set your own fan curve according to your noise/temperature preferences.

• Air cooling of the air cooler type, which is easy to install and does not require maintenance like water cooling systems.
• Compatibility with modern sockets LGA 1700, LGA 1851, AM4, and AM5, so you can use it even when changing platforms.
• Compact fan with dimensions of 100 x 100 x 25 mm, suitable for smaller cases and configurations with limited space around the CPU slot.
• Speed range of 700 – 1700 RPM, allowing quiet operation in idle and more serious airflow during gaming or heavy tasks.
• Rifle Bearing type bearing, ensuring a longer lifespan and more reliable operation compared to basic sleeve solutions.
• Low noise level of only 24.8 dBA, suitable for quiet systems that you want to keep on your desk.
• Standard 4 PIN connector for full PWM control via the motherboard and fine-tuning of fan profiles.
• Clean black design, which fits well in both minimalist and gaming builds without drawing excessive attention.

Who it is suitable for: PURE ROCK SLIM 3 is a good option for budget and mid-range systems, office machines, or compact gaming builds where you want something better than a stock cooler, but without paying for a massive tower. It is suitable if you are after silence and a clean look, rather than aggressive overclocking. It is not the most logical choice for heavy high-end CPUs with constant maximum load and serious overclocking.

The combination of compatibility with current sockets, low noise level, and compact size makes the be quiet! PURE ROCK SLIM 3 a very sensible choice if you are looking for practical, quiet, and unpretentious air cooling for everyday gaming and work.
